Nice work on that shutoff you’re more diligent than most electricians I work with.

It took me far too long to realize the micron gauge isn't measuring size, but pressure. In my head, I was thinking micron was measuring the size of the particles of refrigerant or nitrogen. Instead, its micrometers of mercury, or umHg, and 439 microns converts to 0.008 psi. So really dang low

Here’s a tip on the use of torquing instruments…. as you rotate the tool, you have to have movement of the fastener, and then experience the click. If you put the device onto a fastener, and it clicks right away, you may have way too much torque on the fastener, and not realize it. As long as there is movement before the click, then you know that you have not exceeded the torque specification. If you go back to check a second time, then you’re not going to have movement. However, if you torque these fasteners down without using the torque instrument, and then apply the torque instrument to the fastener, there must….repeat, must be movement.

yep love watching the tire shop guys using the torque wrench after the impact and getting zero movement on any of the lugs. lol

For any stranded wire, you need to torque it down, back it off, then torque it down a second time, especially if using aluminum. That arc burn on the wire is because the wire was lose. Because the unit as a whole vibrates, the chances of that happening again are high.

[@HVACRVIDEOS]

I did that earlier in the video when I installed it. I always run the screws into the wires (tighten loosen than tighten again. Than I loosen and torque down with the torque driver

I've gotten into the habit to just add a port to the liquid line. It adds length to the liquid line if you do cut out the drier, since you also have to cut in a port.

[@Kangenpower7]

Good catch about the compressor with a leaking internal high pressure relief valve. That is a rare thing to find. It will send high pressure and very hot gas into the low side of that compressor, quickly overheating it! One time I was explaining to a customer that the freezer compressor was bad, even thought it was running. I shut off the liquid line valve, and after 5 minutes, it still had not pumped down, and was still running. The amp draw was only about 40% of the maximum rated on that unit. Sadly they did not believe me when I told them the reason for the warm walk in freezer was a bad compressor, bad valves. It was a large chain store restaurant, and they basically told my boss that they would seek another refrigeration company. I can only guess what the next guy looking at their walk in freezer had to say? And did they get fired for telling them basically the same thing? Yes I tried to explain it to them, and my boss was understanding that I was right in condemning the compressor.

Very professional. It's great to see a skilled craftsman at work.

[@ToIsleOfView]

This is a good demonstration of why we can't attract enough service people into the HVAC field. This is extremely hard work! Look at how heavy all those tools are. We have to carry all this weight to the to a blistering roof by hand. The compressor might get boomed to a corner of the roof but then it has to be hand dollied and hand lifted into place. Look at how many tools it takes to do the job. Some of those tools are extremely expensive and high tech. The complicated equipment controls are brand specific and require extra training. Programming a VFD? Plumbers and electricians have nothing compared to this but they command similar wages. All the smart people are seeing this and choosing not to go into HVAC. Wages for experienced HVAC techs need to be 75% higher than plumbers and electricians if we are going to attract the smart people.

You would have to pay that kid $150,000 a year to do my job. And guess what that’s probably not going to happen….. so they’re going to try and get by with people who know about 1/10 of what I know.

@@arthouston7361wages have went to shit for the trades. It’s not the new generation but business owners not willing to pay for skilled labor.

[@arthouston7361]

@@MirrorRealityHD Well that's where you're wrong. It's not the business owners "not being willing" to pay higher wages. It's business owners not being able to pay higher wages, because you can only pay about 25% of your hourly rate in a wage, and if you raise your hourly rate, customers won't use you anymore. From the employee perspective, if you can get a job that pays more elsewhere, why in the world would you be standing on a roof in a 20 knot wind in the middle of Winter working on a rooftop unit, when you can be in your basement playing Fortnite, and as long as you write a couple of apps for the iPhone every year, you can make more than that hvac service technician does. Most commercial customers, be they chain stores, restaurants, or anything else, are searching for the very bottom that they can pay for any given procedure, and because I do a lot of follow-up work on other companies, I can tell you that most of the people coming into the trade have no idea what they're doing, and a giant labor tsunami is heading for the HVAC industry, and it's going to have to crash and burn before it rises from the ashes with better wages.

I’m not an AC guy, but I watch a lot of AC videos for some reason I like them I got a question why does commercial equipment burn out compressors like crazy but residential is usually never the compression

[@TheDimsml]

1:11 I am pretty sure that you should not stick multi threaded wires into those leaf spring screw terminals, no matter how big the actual strands / contacts are, since they will move relative to each other, creep, cause loose connections and it will lead to the same end you have here - poor contact and overheating. Try catching an electrician and asking them if you have to put a copper sleeve over the wire and crimp it before you put them into a leaf spring contact. But yes, you will have to crimp them with a hydraulic crimper, I guess.

[@pnp8849]

Only if it rated "solid CU or AL only". It'll have marking on the device. If there's no marking then you could stick in what ever, assuming it has UL/CE and not stuff you get from amazon.

Seem like you got high oxidation on the supply breaker since you got 206V on 1&3. I normally disconnect all the load and then cycle on/off the supply breaker several times until I get 208V or even across. Most often is 208V unless the main breaker is oxidizes too but that's rare.

[@HVACRVIDEOS]

Thank you very much my friend

[@HVACRTECH-83]

One thing id add for anyone who doesnt know, low suction pressure is just as bad as high discharge pressure in terms of how compressors get killed. Wether it be from low charge,restrictions, or low airflow,doesnt matter. Compressors are refrigerant cooled and low suction pressure/temp = lower mass flow rates=improper cooling of the motor regardless of the lower temps. If restriction or low airflow is the cause, this raises your compression ratio drasticly and high discharge temps result during long run times with the lack of cooling. Compressors can even run hotter discharge from very low charge as well. You may have a very cold evap ex.20f sat temp, but it will pick up so much heat so fast you could end up with 50f superheat and a 70f or higher vapor entering compressor which is too warm. Then theres liquid floodback and slugging which are pretty high up on the list of killers with multiple causes to them both. Also while rare, a rv bypassing slightly to the point where no one notices theres an issue but you have vapor entering compressor at 80,90,100+f for long periods.

[@gregmercil3968]

I recently replaced a failed LG compressor under warranty on a Lennox RTU that was less than a year old. Breaker was tripped. The compressor got so hot that it melted it’s own wires to the side of the compressor, shorting itself out. The wiring harness was melted/fused to the terminals on the compressor. I’m not entirely sure what happened, but after the old compressor was removed I managed to pry the wiring harness off (wasn’t about to do that when still pressurized with refrigerant) to test it, if I remember right the run and common windings were internally shorted to each other. LG definitely makes some of the crappiest compressors.

When you have a VFD, checking voltage to the compressor doesn't tell anything about the input voltage. In those cases, you need to check both voltages at input and at compressor level. By the way, with VFD is quite useless to check voltage at compressor level. Usually VFDs have internal diagnostics (should display an error).
